From: =?ISO-8859-1?Q?Kir=E1ly?= on 24 May 2010 20:17 I'll be traveling soon and would like to keep scans of my passport, birth certificate, airline tickets, etc online (encrypted of course) in an easily accessible place in case I lose all of what I am carying with me. If I find myself in need of those online docs, I would probably be accessing them on a Windows computer. Can anyone suggest how I can encrypt those scans on my Mac (10.5.8) so that they can be easily decrypted on a Windows machine? Preferably without having to install additional decrypting software on the Windows machine? I know nothing at all about Windows and so I have no idea what decrpytion tools are preinstalled. I have looked at OS X's command line zip tool, but I am a little wary of it because its man page says that its encryption method is "considered weak". I have looked into various online secure document sharing services (Mozy et al) but they all seem overly complicated and they like to use their own encryption algorithms - maybe I'm paranoid but I'd rather use my own. TIA for any help. -- K. Lang may your lum reek.

I am only aware of two programs that can encrypt files on one OS and decrypt them on the other type of OS: Not freeware: Stuffit Deluxe for Mac and Stuffit for Windows. Both products have a 30 day free trial if you provide a credit card number. Freeware: Meo from NCH Software. There is a version for Intel Macs, PPC Macs and Windows.

I've dealt with this problem because my son and one of my daughters are Mac users, while the other daughter is a Windows user, and we want to share encrypted files. My wife and I have both PPC and Intel Macs. I looked at MEO. It is unsatisfactory unless everyone on the Mac side is using an Intel Mac. Perhaps they've fixed this, but when I last checked perhaps six months ago a file encrypted on a PPC Mac with the PPC version of MEO would decrypt to gibberish on an Intel Mac or on a Windows machine (each with its appropriate version of MEO), and (vice versa) a file encrypted on an Intel Mac or on a Windows machine would decrypt to gibberish on a PPC Mac. Different PPC Macs could correctly decrypt each other's encrypted files, and likewise there was no problem with different Intel Macs, or going between Intel Macs and Windows machines. I suspect somebody got the endian thing wrong. I e-mailed the NCH Software people about the problem but got nowhere. Since our household has both PPC and Intel Macs, MEO was unusable for us. If you only have Intel Macs, it probably will work OK. Since then I have come upon TrueCrypt. The Mac version is Universal (works on both PPC and Intel Macs), and there is one Windows version. Encrypted files can successfully be exchanged in any direction among PPC Macs, Intel Macs, and Windows machines. Warning: Make the disk images much larger than you think will be necessary. You could put both the Mac and Windows versions of the program on a USB Flash drive, along with your encrypted files. Then when you use someone else's computer, provided you are allowed to install the appropriate version of TrueCrypt, everything should work smoothly. As an alternative, you could use Dropbox to store both your encrypted files and the Mac and Windows versions of TrueCrypt. Then all the other computer needs is a web browser, to access Dropbox, and you can leave your USB Flash drive home.
